NanaWall Systems has introduced the WA67, a folding glass wall system to mount extruded aluminum cladding to a solid wood core with a spacer bar to secure the materials together. This feature allows for different expansion rates between materials to avoid cracking for durability in any climate.
The WA67 is built to withstand any changes in weather due to the NanaWall proprietary evaporation chamber engineered to allow the wood and aluminum to expand and contract. The extruded aluminum is attached to the wood using the back ventilated, rain screen principle to protect and isolate the cross-grained triple laminated wood on the inside.
An enhanced option is available featuring triple-seals, triple-paned glass and deeper door panels for even higher weather performance that reaches U-value of .18 and a Solar Heat Gain Coefficient of .20 for energy efficiency. Inward or outward opening door panels are also available for more design flexibility. The system can be top hung or floor supported and is life-cycle tested to open and close more than 20,000 times without failure, opening even in extreme temperatures.
